Description

この発明は、不同沈下した建物をジャッキアップするための鉄板フーチング方式による不同沈下修正工法に関するものである。  The present invention relates to a non-settlement subsidence correction method using an iron plate footing system for jacking up a non-sinking building.

従来、建物を建築するためには、まず最初に建てる土地の地盤調査をし、地耐力を計算した後、基礎や杭を設計します。つまり建物の重さより地耐力が必ず大きくなけれは建築確認がとれません。  Conventionally, to build a building, the ground of the land to be built is first investigated, the earth strength is calculated, and then the foundation and pile are designed. In other words, if the earth bearing capacity is always greater than the weight of the building, the building cannot be confirmed.

しかしながら、建物に対する必要地耐力に関しては、建物の重さプラス余裕が必要となります。このためプラス余裕をどの程度にするか、しばしば問題になります。  However, with regard to the required ground strength for the building, the weight of the building plus a margin is required. For this reason, it is often a question of how much plus margin you can afford.

もちろん堅固な地盤であれば問題はありませんが、建物の重さに対して地耐力に余裕がない場合は地盤改良や鋼管杭等の工事が必要になります。さらに、新造成地や土質不良地等の地盤においては、部分的に地耐力の低い場所が存在するため、不同沈下が発生しやすいと云う問題をかかえていた。  Of course, there is no problem as long as the ground is solid, but if there is not enough ground strength for the weight of the building, ground improvement and construction of steel pipe piles will be required. Furthermore, in the ground such as newly developed land and poorly soiled land, there is a part where the ground strength is partially low, so that there is a problem that uneven settlement is likely to occur.

このように、地耐力を十分に考慮して建物を建築した場合であっても、経年変化により不同沈下が発生して建物が傾くと云う問題が発生していた。  As described above, even when the building is constructed with sufficient consideration for the earth resistance, there is a problem that the building is inclined due to the secular change due to the secular change.

従来から、このように建物が傾いた場合は、不同沈下した建物の直近に、新しい基礎を構築しその基礎にジャッキを据付け、建物をジャッキアップさせる方法や、不同沈下した建物の直近に、鋼管杭を支持地盤まで打ち込むと共に、その鋼管杭の上部にジャッキを据付け、建物をジャッキアップさせる方法等のアンダーピニング工法が知られているが、いずれの方法も、多大な費用と長期間の補修工事が必要となる等の問題が発生していた。  Conventionally, when a building is tilted in this way, a new foundation is built in the immediate vicinity of the building that has been sunk, a jack is installed on the foundation, and the building is jacked up. Underpinning methods such as driving the pile to the support ground and installing a jack on the upper part of the steel pipe pile to jack up the building are known, but both methods are expensive and require long-term repair work. There was a problem such as needing.

そこで、この発明は建物が不同沈下した場合の補修工法として、従来から行われてきたアンダーピニング工法に頼ることなく、建築初期に建物の耐圧基礎の下部に、耐圧基礎の外周底面より大きく構成した鉄板を敷いておく事により、地盤に対する建物の載荷重を少なくすると共に、建物をジャッキアップする際のジャッキ有効底盤として利用することができる等、鉄板フーチング方式による不同沈下修正工法を提供することを課題としている。  Therefore, the present invention is configured as a repair method in the case where the building sinks unevenly, and is configured to be larger than the outer peripheral bottom surface of the pressure-resistant foundation at the bottom of the building's pressure-resistant foundation in the early stage of construction without relying on the conventional underpinning method. Providing a non-settled subsidence correction method using an iron plate footing method, such as reducing the loading load of the building against the ground by laying an iron plate and being able to use it as a jack effective bottom plate when jacking up the building It is an issue.

かかる課題を達成するために、請求項１に記載の発明は、建物の耐圧基礎の下部に耐圧基礎の外周底面より大きく構成した鉄板を敷くと共に、建物に不同沈下修正金具を固定し、鉄板の上面にジャッキを据付け、建物と一体になるように固定した不同沈下修正金具をジャッキにて押上げる事により建物を持上げるようにした事を特徴とする。  In order to achieve such an object, the invention described in claim 1 lays an iron plate that is configured to be larger than the outer peripheral bottom surface of the pressure-resistant foundation at the lower part of the pressure-resistant foundation of the building, It is characterized in that the building is lifted by pushing up the non-settlement correction fitting fixed with the jack on the upper surface and fixed so as to be integrated with the building.

請求項２に記載の発明は、請求項１に記載の工法に加え、鉄板を建物の耐圧基礎下部の四隅に配置したことを特徴とする。  The invention described in claim 2 is characterized in that, in addition to the construction method described in claim 1, iron plates are arranged at the four corners of the lower part of the pressure-resistant foundation of the building.

請求項３に記載の発明は、請求項１に記載の工法に加え、鉄板を建物の耐圧基礎下部の中心部を除く全周に配置したことを特徴とする。  The invention described in claim 3 is characterized in that, in addition to the construction method described in claim 1, an iron plate is arranged on the entire circumference except for the central part of the lower part of the pressure-resistant foundation of the building.

請求項１に記載の発明によれば、建物の耐圧基礎の下部に耐圧基礎の外周底面より大きく構成した鉄板を敷くと共に、建物に不同沈下修正金具を固定し、鉄板の上面にジャッキを据付け、建物と一体になるように固定した不同沈下修正金具をジャッキにて押上げる事により建物が持上がるようにしため、ジャッキ有効底盤の面積を最大限に広く利用することが可能となり、従来のように、不同沈下した基礎の直近に鋼管杭を支持層まで打ち込み、上部をコンクリートで固めた上にジャッキを据付け、建物のジャッキアップを行うと云うようなアンダーピニング工法が不要となると共に、工期の短縮につながり、大幅にコストの低減を図ることができる。  According to the invention described in claim 1, an iron plate configured to be larger than the outer peripheral bottom surface of the pressure-resistant foundation is laid on the lower portion of the pressure-resistant foundation of the building, the non-uniform subsidence correction metal fitting is fixed to the building, and a jack is installed on the upper surface of the iron plate, Since the building is lifted by pushing up the non-settlement fixing bracket fixed so as to be integrated with the building with the jack, it is possible to use the maximum area of the jack effective bottom board as much as possible. In addition, underpinning methods such as driving steel pipe piles to the support layer in the immediate vicinity of the unevenly settled foundation, solidifying the upper part with concrete, installing jacks, and jacking up buildings are unnecessary, and shortening the construction period This can lead to a significant cost reduction.

請求項２に記載の発明によれば、鉄板を建物の耐圧基礎下部の四隅に配置したことにより、地盤の地耐力にバラツキが発生する新造成地や土質不良地等の土地に対して、耐圧基礎下部の四隅に配置する鉄板のサイズと厚さを変えることにより、柔軟に対応することができるようになると共に、建物が不同沈下した際には、四隅に配置した鉄板の上部にジャッキを据付け、四隅の不同沈下した度合いに応じて、それぞれのジャッキを個別に調整することが可能となるばかりでなく、工期の短縮につながると共に、大幅にコストの削減を図ることができる。  According to the invention described in claim 2, by placing the steel plates at the four corners of the lower part of the pressure-resistant foundation of the building, the pressure resistance against land such as newly formed land or poorly soiled land where the ground strength varies. By changing the size and thickness of the steel plates placed at the four corners of the bottom of the foundation, it becomes possible to respond flexibly, and when the building sinks unevenly, a jack is installed on the top of the steel plates placed at the four corners In addition to being able to adjust each jack individually according to the degree of uneven settlement at the four corners, the construction period can be shortened and the cost can be greatly reduced.

請求項３に記載の発明によれば、鉄板を建物の耐圧基礎下部の中心部を除く全周に配置したことにより、建物が不同沈下して複数のジャッキで建物をジャッキアップさせる場合でも、複数のジャッキの底盤が一体の鉄板となっているため安定した状態で建物をジャッキアップすることが可能になると共に、工期の短縮と、大幅にコストの削減を図ることができる。  According to the invention described in claim 3, even when the building is sunk unevenly and the building is jacked up with a plurality of jacks by arranging the iron plate all around the center of the building at the lower part of the pressure-resistant foundation, a plurality of jacks are used. Because the bottom plate of the jack is an integrated steel plate, it is possible to jack up the building in a stable state, shorten the construction period, and greatly reduce the cost.
